HORATIO CLARKE, OF DEDHAM, MASSACHUSETTS.

BOBBIN.

Specification of Letters Patent No. 9,814, dated June 28, 1853.

To all whom may concern Be it known that I, I-IoRATIo CLARKE, of Dedham, in the county of Norfolk and State of Massachusetts, have invented a certain new and useful Improvement in the Manufacture of Spooling or Various other Bobbins; and I do hereby declare that the same is fully described in the following specification and represented in the accompanying drawings, letters, figures, and references thereof. y

Of the said drawings, Figure 1, denotes a side elevation of a spooling bobbin made on my improved plan. Fig. 2, is a longitudinal and central section of it. Fig. 3, is a view of a bobbin, made with my improvement, but somewhat modified in construction from that seen in Figs. l and 2, as will be hereinafter explained.

In the said drawings each of the bobbin heads A, B, is composed of a wooden disk a, cemented or glued firmly to a disk b of raw hide, or other flexible material, possessing the properties thereof, or ability to resist wear and breakage or injury from a blow. This raw hide protector may be` fixed on the inner or outer side of the bobbin head. In Fig. 3, it is exhibited as arranged on the external side of it.

An immense waste occurs in the use of bobbins as usu'all'y made. Then constructed with each of their heads made of two pieces of wood laid on one another and glued together, and with the grain of one crossing that of the other, as they are sometimes made they are not free from objections, as they soon become broken so as to render them useless; for where both disks are made of a material liable to crack by a blow or a fall upon a hard substance, the bobbin head soon gets destroyed or greatly damaged while in use.

Bobbin heads as I have understood, although I have never seen such, have been made entirely of raw hide, but such are too expensive, and not stiff enough for ordinary use, and therefore they cannot be employed to advantage. The manner in which bobbins are treated, they being thrown into boxes, or often dropped on a fioor, requires that their heads should be constructed in some manner, possessing qualities of stiffness, and capable of withstanding not only the effects of such blows, but the wear that occurs to them when used on the spooling machine.

I do not claim the making a bobbin head of two layers or disks of wood glued or cemented together, nor do I claim the invention of constructing one of raw hide entirely, but

`What I do claim as my improvement is rThe making' the bobbin heads described, viz., of a combination of wood and rawhides or other material having like properties, whereby the head is not only cheaply constructed, but rendered properly stiff and capable of resisting the effects of blows, falls, or wear as above stated.

In testimony whereof I have hereto set my signature, this eleventh day of January HORATIO CLARKE. Iitnesses ELIZABETH STONE, HENRY SMITH.
